In-House Marketer vs Construction Marketing Agency

At some point, most growing construction companies ask the same question: should we hire a marketing person, use an agency or keep working with separate suppliers? There is no one-size-fits-all answer. An in-house hire can be brilliant if you already have a clear strategy and the right support around them. An agency can be faster if you need several skills at once. Multiple suppliers can work, but only if someone is managing the whole picture. This guide gives you the plain-English comparison so you can choose the setup that fits your business, not just the one that sounds cheapest.

The quick answer

The right setup depends on four things: the skill gaps you need to fill, your budget, how fast you need results, and who is accountable for them.

• Skill gaps. One channel to fix, or the whole system to build.
• Budget. What you can commit each month, and what a job is worth to you.
• Speed. How quickly you need the diary filling.
• Accountability. Who owns the strategy, the reporting and the result.

Get those four straight and the choice usually makes itself. Before you decide, it helps to know what good marketing looks like for a construction company so you are hiring against a plan, not a hunch.

Option 1: hire an in-house marketing person

Bringing marketing in house gives you someone who lives and breathes your business. They know the projects, the team and the customers, and they are there every day.

• Best for: companies with a clear strategy that need someone to run it day to day.
• The catch: one person is strong in one or two skills and average in the rest. Marketing needs strategy, website, SEO, ads, content, video and reporting, and few people do all of that well.
• The real cost: salary plus National Insurance, pension, holiday cover, tools and management time. It is more than the advertised figure.

An in-house hire works best when they have support around them, whether that is freelancers, an agency or a clear brief from you.

Option 2: a specialist construction marketing agency

A specialist agency that only works with construction and civils gives you a team of skills for one monthly fee. They already know your sector, so there is less to explain.

• Best for: owners who want the whole system built and run without hiring a team.
• The advantage: several specialists at once, sector knowledge on day one, and cover if someone is away.
• The catch: you need to pick a partner who reports on booked work, not clicks. Our guide to choosing a trades marketing agency covers what to look for.

For construction and civils, our Preferred Contractor Programme is £2,500 + VAT a month and joins up strategy, website, SEO, ads and follow-up as one system. For smaller trades businesses, the Booked Solid System is £1,500 + VAT a month.

Option 3: multiple suppliers

Using separate suppliers means picking a web person, an SEO person and an ads person, each chosen on merit. It can work well, and it spreads your risk across a few relationships.

• Best for: companies with someone in-house to brief and coordinate them.
• The advantage: you buy each skill from a specialist and can swap any one out.
• The catch: nobody owns the whole picture. The strategy drifts, reporting does not join up, and the coordinating usually lands on you.

Option 4: a generalist agency

A generalist agency covers every sector and can turn its hand to most channels. If you have a clear plan already, they can execute it.

• Best for: businesses with a defined strategy that just need delivery.
• The advantage: breadth of skills under one roof.
• The catch: you often pay for their learning curve on construction. They may not understand your seasonality, your lead quality or how you actually win work.

Cost and risk comparison

Prices are typical and vary by scope. Use this to compare the shape of each option, not to fix an exact figure.

Option	Typical monthly cost	Skills covered	Main risk	Who is accountable
In-house marketer	Salary plus tools and on-costs	One or two done well	Gaps in the other skills	You and the hire
Specialist construction agency	From £1,500 + VAT (trades) to £2,500 + VAT (civils)	Full system	Choosing the wrong partner	The agency
Multiple suppliers	Varies, often several small fees	Broad, but siloed	Nobody owns the whole picture	You
Generalist agency	Varies by retainer	Broad, sector-light	Learning curve on construction	The agency

When to hire in-house

Bringing marketing in house makes sense when:

• You already have a clear strategy and know what needs doing each week.
• You have enough steady work to justify a full-time salary.
• The role is mostly one or two skills, such as content and social, that one person can own.
• You have someone senior to manage them and fill the gaps.

When to use an agency

An agency tends to be the better fit when:

• You need several skills at once and cannot justify hiring for each.
• You want results faster than a hire, an induction and a ramp-up allow.
• You want one team accountable for the outcome, not a set of suppliers to chase.
• You want sector knowledge from day one rather than teaching it. A specialist knows what your website needs to convert without being told.

Questions to ask before choosing

Before you commit to any option, get clear answers to these:

• What skills do we actually need, and which are missing today?
• Who will own the strategy and hold it together?
• How fast do we need results, and can this setup deliver in that window?
• How will we measure success: booked jobs and cost per lead, or just activity?
• If this does not work, how easily can we change course?

Whichever way you lean, the setup matters less than the plan behind it. A good 2026 marketing plan tells you what needs doing first, and that in turn tells you whether a hire, an agency or a mix is the right way to get it done.
